The present invention relates to a device for measuring user's grip strength.
A conventional device for training grip strength generally includes a biasing member and the user holds the biasing member and tries to compress the biasing member so as to exercise the muscles of hands. A conventional measuring device uses a rack to drive a gear which is connected with an arm which is pivoted to point one of the measuring marks. The user then reads the marks to obtain the data of the force that applied to the rack.
The present invention intends to provide a grip measuring device that is used as a game set and the users grip and pull the handle, a precise value of the grip strength is displayed.
The present invention relates to a device for measuring grip strength, and comprises a checking unit received in a base and a shaft is located in the base. A cable is wrapped on the shaft and includes a first end and a second end. A disk is connected to an end of the shaft and includes a plurality of protrusions extending radially outward from a periphery thereof and recesses are defined between the protrusions. A detection member is located beside the disk and the protrusions are movable through the detection member when the cable is pulled by the users. A transferring unit is connected to the base and includes a fixed part and an operation unit is movably connected to the fixed part. A rod is movable with the operation unit and connected to the first end of the cable. A biasing unit is used to return the rod.
The primary object of the present invention is to provide a grip strength detection device which includes a handle for the user to hold and apply a force, the movement of the rod drives a cable which rotates a shaft. A disk is connected to an end of the shaft and includes protrusions which pass through a photoelectric sensor so as to detect the angular distance that the disk travels. The angular distance is transferred into value of the grip strength.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
A transferring unit 5 is connected to the support unit 51 and includes a fixed part 6 and an operation unit 7. The support unit 51 includes a top 52 and a lower part 53 which is connected to an underside of the top 52. The lower part 53 includes a hole 54 and the first end 31 of the cable 3 extends through the hole 54. The shaft 2 is connected to a bearing 55 which is connected to an underside of the lower part 53. The fixed part 6 is connected to the top 52 and includes a top rod 61 and two sides 62. Each side 62 includes a groove 621 defined in an inside thereof and the top rod 61 is fixedly connected between the two facing grooves 621.
The operation unit 7 includes a handle 71, two blocks 72 connected between the handle 71 and a connection plate 73 which is parallel to the handle 71. The two blocks 72 are movably engaged with the grooves 621 of the two sides 62. The rod 8 has one end connected to the connection plate 73 and the other end of the rod 8 extends through the top 52 and is connected to the first end 31 of the cable 3. The biasing unit 9 includes a spring 92 and a lower member 93 which is connected with a first end of the spring 92. The spring 92 is mounted to the rod 8 and a top disk 91 is fixed on the rod 8, a second end of the spring 92 is stopped by the top disk 91 which is in contact with the top 52. The biasing unit 9 is used to returns the rod 8 when the rod 8 is released.
A cylindrical member 562 has one end connected to the underside of the top 52 and the spring 92 is received in the space 563 in the cylindrical member 562. A tube 56 is connected to the other end of the cylindrical member 562 and a passage 561 is defined through the tube 56 so that the lower member 93 is movably received in the passage 561. Two locking nuts 564 are cooperated with two bolts are connected to an underside of the tube 56 so as to restrict the lower member 93 from dropping off from the passage 561. The rod 8 includes a threaded section which extends through the lower member 93 and is connected to a nut 81. The first end 31 of the cable 3 is fixed to the threaded section.
As shown in
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
